摘要
目的 :探讨脊髓型颈椎病 (CSM )合并后纵韧带退变 (DPLL)的病因和病理变化过程。方法 :回顾总结 35 0例CSM手术所见 ,对术中切除的 182例DPLL送病理切片行光镜观察。对 2例正常人的颈椎后纵韧带 (PLL)和 5例典型的DPLL标本进行了电镜观察。结果 :后纵韧带正常者 16 8例 ( 4 8% ) ,DPLL182例 ( 5 2 % ) ,其中纤维化增厚 86例( 2 4.6 % ) ,纤维化合并软骨化 2 1例 ( 6 .0 % ) ,纤维化合并骨化 75例 ( 2 1.4% )。结论 :CSM合并DPLL者高达到 5 2 % ,其病因呈继发于颈椎间盘退变。DPLL退变过程分为 3个阶段 :纤维化增厚、软骨化和骨化。
Objective:To study the etiology and the pathological process of the cervical spondylotic myelopathy(CSM) combined with DPLL.Methods:350 cases of operated CSM were analysed respectively.DPLL of 182 cases were excised and investigated with light microscope. Speciment of 2 normal cervical posterior longitudinal ligment(NPLL) and 5 typical DPLL were investigated with electron microscope.Results:There were 168(48%) with normal PLL and 182(52%) with DPLL,in which there were 86(24.6%) with fibrosis,21(6.0%) with fibrosis combined with cartilaginification and 75(21.4%) with fibrosis combined with ossification. Conclusion:The incidence of CSM combined with DPLL is 52%,and the etiology is secondary to the degeneration of cervical intervertebral disc.The degenerative process can be divided into three stages:fibrosis,cartilaginification and ossification.DPLL is one of the reasons of the OPLL formation.
